Table 1: This table shows the case number (1 to 25), gender, age, diagnosis, type of hemipelvectomy, and in patients who underwent internal hemipelvectomy, its functionality based on the MSTS system. Non-neoplastic diagnoses are noted.

CEH = classical external hemipelvectomy. MEH = modified external hemipelvectomy. EEH = extended external hemipelvectomy. IH = internal hemipelvectomy. CoEH = compounded external hemipelvectomy. (Enneking and Dunham’s classification I/II/III/IV), and conversion to classical external hemipelvectomy = → CEH. Function score: dark gray for patients undergoing external hemipelvectomy, light gray for patients undergoing internal hemipelvectomy without follow – up for evaluation, and black in patients who died.
